<h2>Active Construction Plane</h2>
The definition of the design plane
    (A User Coordinate System - UCS).
  For the definition you can use a plane or a pre-defined plane.
    (Pre-defined planes: RX or RY or RZ).
    (see CAD-PLN, <a href="CAD_PLN_en.htm">Definition planes</a>)
  The origin point of the chosen plane is the new coordinate origin.
  In relation to the design plane are now:
   - Coordinate data
   - Displaying positions

   The display of the mouse position can be relative or absolute.
     Relative: (Default Setting) the coordinates in the new coordinate system;
     Absolute: Sets all coordinates to absolute origin relative.
   Toggle the radio button between &quot;rel&quot; and &quot;abs&quot; next to the display of the mouse position.

   To reset to the absolute coordinate system - Reset ConstrPlane

Example:
R20 = P(100 0 0) DR DY
# Zero in 100,0,0; new X-axis in 0,10,0
R20
# Enable use of a new coordinate system.


See Example model sample_ucs1.gcad

<h2>Reset ConstrPlane</h2>
Reset to the absolute coordinate system

Plane 0 defines the absolute coordinate system.
   Create with output code &quot;R0&quot;
